About our air source heat pumps in Colnbrook
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. We are often asked to deal with replacing a combi boiler with a heat pump and plans to switch to electric heating with a heat pump, across radiator systems, underfloor heating and air-to-air heat pumps.
In a place like Colnbrook, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Why act early in Colnbrook

A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before we start, with VAT shown clearly.

How the job changes from property to property
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small and that matters for comfort and running.
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. They don’t heat hot water so you’ll need another way to heat it.

FAQs for Colnbrook
Is a heat pump in Colnbrook permitted development?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Colnbrook Conservation Area, close to central Colnbrook. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the planning department at Slough council, normally the authority for Colnbrook first.
Is the heat pump grant available in Colnbrook?
Yes, if the home and the heat pump meet the scheme’s rules: Colnbrook is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
After we have gone
Aftercare is straightforward, and it makes the next visit easier:
- Keep the outdoor unit clear all year
- Do not block radiators or indoor units with furniture
- Find out the grant position at the survey
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that is normal.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
